“Best filter i have had”

“Silent. You can keep the nozzle slightly under the surface and it'll create surface agitation.
* Bio media, sponge, customizable, etc etc
* Cons:
* I bought it during Black Friday at PetSmart. Otherwise, I would never have bought it. It's really expensive.”

“And this is the canister filter I use, I have a 75 gallon tank so depending on your tank size you could get the smaller version https://www.petsmart.com/fish/filters-and-pumps/filters/fluval-407-performance-canister-filter-5290152.html”

“I have both the FX4 and 407. My personal opinion is that the FX4 works best in 6ft long tanks, unless you need strong water flow. It's very powerful. The 407 is suitable for a tank that size.”

“I never figured out personally what was going on, but I moved a few months ago and when I set up the filter at my new place it stopped doing this. No idea what changed but might be worth moving the placement around or something, I dunno, lol.”

“I have Fluval 407 too, just clean the foam to remove the big debris. When you siphon clean the gravel, drain it in bucket, then open your canister, pull out the foam cartridge only, take out the foam and wash it in the bucket with the aquarium water.”

“I have two sponge filters and the Fluval 407 canister, so ordering purigen now! Thank you :)”
Redditⓘ good to know
“Sounds like air/air bubbles in the canister. You may need to open it up and add more water or turn it off and reprime. You shouldn't have that trickling water sound. If you just have that offgasing noise, it can be caused by air bubbles and will often dissipate over time.”

“I agree, I run fluval 407s on most of the tanks, they range from 20g to 75g, and for the larger ones, I have FX6's. Dont get me wrong though, ive used sponges and got very good results throughout my fish keeping journey. Personally, I really like the options a canister filter gives you.”
